Kinetics of Strongly Nonequilibrium Magnon Gas Leading to Bose-Einstein Condensation [PDF]
Журнал нано- та електронної фізики, 2017 Kinetic equations describing nonequilibrium magnon gas under the action of parametric pumping are considered with an account of kinetic instability processes. These processes strongly influence condition of magnon Bose-Einstein condensate formation.

Physics Letters B, 2023 Recent experimental efforts were made to explore the Bose-Einstein condensation in multi-α system using the heavy-ion collisions. This Letter provides an explanation why no signatures were observed and a guidance for future experiments. More precisely, a

Nonextensive Bose–Einstein condensation model [PDF]
Journal of Mathematical Physics, 1999 The imperfect Boson gas supplemented with a gentle repulsive interaction is completely solved. In particular, it is proved that it has nonextensive Bose–Einstein condensation, i.e., there is condensation without macroscopic occupation of the ground (k=0) state level.

Space-borne Bose–Einstein condensation for precision interferometry [PDF]
Nature, 2018 Owing to the low-gravity conditions in space, space-borne laboratories enable experiments with extended free-fall times. Because Bose–Einstein condensates have an extremely low expansion energy, space-borne atom interferometers based on Bose–Einstein ...

Bose-Einstein Condensation of Europium. [PDF]
Physical Review Letters, 2022 We report the realization of a Bose-Einstein condensate of europium atoms, which is a strongly dipolar species with unique properties, a highly symmetric [Xe]4f^{7}6s^{2} ^{8}S_{7/2} electronic ground state and a hyperfine structure.

Bose–Einstein condensation in the Rindler space
Physics Letters B, 2015 Based on the Unruh effect, we calculate the critical acceleration of the Bose–Einstein condensation in a free complex scalar field at finite density in the Rindler space.

Coherence and Optical Emission from Bilayer Exciton Condensates
Advances in Condensed Matter Physics, 2011 Experiments aimed at demonstrating Bose-Einstein condensation of excitons in two types of experiments with bilayer structures (coupled quantum wells) are reviewed, with an emphasis on the basic effects. Bose-Einstein condensation implies the existence of

Color confinement and Bose-Einstein condensation
Journal of High Energy Physics, 2021 We propose a unified description of two important phenomena: color confinement in large-N gauge theory, and Bose-Einstein condensation (BEC). We focus on the confinement/deconfinement transition characterized by the increase of the entropy from N 0 to N ...

Bose–Einstein condensation on curved manifolds
New Journal of Physics, 2020 Here we describe a weakly interacting Bose gas on a curved smooth manifold, which is embedded in the three-dimensional Euclidean space. To this end we start by considering a harmonic trap in the normal direction of the manifold, which confines the three ...
